To LU whom vz'zf may concern lle it known thatl, 'lnoinxs F. illumini', a citizen of tho United States, residing at New York, in the county of New" York Vand State of New `York, have invented a certain new and useful Improvement in alethods ot` Forming Integral Flanges on Bodies ot' Ductile Metal, of which the following is a specitieation. i

The invention is a lnethod ot forming a flange upon a pipe, sheathing, rod or other elongated body of dnetile nietal having` the quality ot integrally uniting' hy pressure when cold such as lead-whieh flange, among other speeial purposes, may serve as .nieans for closing a joint between the pipe, shaithing or rod and any object receiving the saine, or through which the saine niay pass.

Tn the :weoinpanying drawings-Figure l is a sectional view ot' an electric eondi'ietor, having a lead sheathing', upon which sheathing; the ilange is formed, showing the inode o't causing the inaterial ot the tlange to .weld or cohere to the material ot the sheathing. Fig. Q a siinilar view. snowing the inode ot' consolidating the material of the flange. Figli. I- is a similar view, showing the conn pleted tlange in its receptacle, and Fig'. l shows the sheathed. conductor withthetlange formed thereon separate troni the receptacle and in perspective.

Siniilar letters of reference. indicate like parts.

My method is herein illustrated hy the formation ot' a lead tlangeonthelead sheathing; A ot' an electrical line conductor B, provided with the usual insulating,r envelop (l. It is, oit course, to he understood, that any other elongated body ot ductile metal having' the quality of integrally uniting by pressure when cold-such as a lead pipepis within iny invention. ln order to forni the flange, l insert the conductor ll through an opening' in a hlock D, in which is a cavity ll, the depth and diameter ot' which may de terniine the sine ot the flange. then place in the bottoni ot the cavity a quantity ot' lead` lilauieiits F of the saine inetal-coinn'ionl y known as lead floss-aud hy means of a tapered tool G, l force the tloss innnediately adjacent to the lead sheathing into ephesion therewith, so that the consolidated floss and the sheathing heeoine practically integral. I then, with a wider nosed tool H, consolidate the floss elsewhere in the cavity, as shown in Fig 2. As soon as one layer' ot loss thus caused to cohere and unite integrally with the sheathing and is consolidated, l introduce another layer into the cavity and repeat the operation, and thus continue adding' successive layers until the flange is completed.

The conductor with the flange I formed thereon and integral therewith, may then, it desired. he removed :t'roin the block D. ln such event, the block D serves only as a inold Vtor the tlange. But instead of inaking the cavity in hloek D, l may inake it in any ohject in which the conductor or pipe is to lie permanently secured, as, for eX- aniple, a coupling sleeve in the Case of the pipe, or a junction hor; or insulator in case of the sheathed conductor. rl`he flange I then remains permanently in the object and closes the joint. i

I claini:

l. The i'net'hod ot torniing an annular flange integrally with and upon an elon- `gated hody ot ductile inetal having the quality ot' integrally uniting' by pressure when cold, which consists in insertingr said hody into a inold having' a cavity of piede terinined diaineter and depth, introducing a. inass of tloss of said inetal into said cavity, causing the saine to cohere with and around said'body, and consolidating' the remainder ot said inass.

Q. The method ot formingl an annular flange integrally with and upon an elongated body of ductile nietal having the quality of integrally uniting by pressure when cold, which consists in inserting` said body into a inold having a cavity ot predetermined diameter and depth, introdncing,A a inass ot tloss ot said metal into said cavity, partially to till the saine, causing said inass to eohere with and around said body, Consolidating the` remainder of said mass, introducing a second inass of floss and repeating the operation. and so on successively until said liange is completed.

ln testimony whereof I have aixed my signature in presence of two witnesses.
